PRESSURE-BUTTON.

Application filed December 3.0, 1913.

To all whom it may concern:

Be it known that I, JULES Anrrnin JonoN, a citizen of the Republic of France, residing at Paris, 36 Rue Etienne Dolet, in the Republic of France, manufacturer, have invented certain new and useful Improvements in Pressiu'e-Buttons, of which the following is a specification.

This invention relates to improvements in the manufacture of pressure buttons in order to simplify their construction and to obtain an assembling of the component parts which will permanently resist the action of the st ain from without. For such purpose, the female portion of the button consists of a disk of which the peripheral part is out out in the fornrv of a star the projections of which are inwardly curved so that their free ends provide between them a space of a diameter somewhat inferior to the diameter of the bulged part of the male portion of the button which is to be engaged'therein under the influence of pressure.

Three embodiments of this invention are shown by way of examples in the accom-- panying drawings, in which Figure 1 is avertical section of the male and female portions of the} button accord ing to one embodiment. Fig. 2 is a plan of the female portion. Fig. 3 shows the two portions of the button assembled together and assumed to be under the influence of a lateral pull; the relative inclination of such portions being purposely exaggerated. Figs. 4 to 9 show difierent stages of the formation of a second embodiment of this invention. Fig. 4 is an elevation of a blank cut out in the shape of a star having four projections, for the manufacture of the female portion. Figs. 5, 6 and 7 are transverse sections of the blank which forms such. female portions at different stages in the method of manufacture. Fig. .8 shows the said female portion finished both in cross section and in plan. Fig. 9 is a section of the male portion of the button. Fig. 10 is a vertical section showing the two portions assembled together according to the third embodiment of this invention. Figs. ll'and 12 show in plan both such portions separately.

In the first cmlmdiment. the male and female portions are each made up of a simple metal disk. F orthe male portion. the disk 1 is so stamped out that its central part forms a large hollow head 2 having a lateral bulge; its peripheral portion is provided Specification of Letters Patent.

with several holes through which it is secured by sewing. For the female portion, the periphery of the disk & is so stamped out that it forms several projections 5; after the stamping out of the central part of the disk in the shape of a cup, such projections are curved inwardly so as to form beads 6 which constitute a divided and extensible socket in essentially the form of aring into which the head of the portion 2 can only enter by causing the projections 5 to yield to some extent. The bottom of the cup is provided with holes 7 for the purpose of fixing such portion by sewing; such holes arelocated in front of the spaces between the projections 5 in order to facilitate the passage of the needle and thread when the sewing is made.

In case the buttons are to be secured to continuous ribbons to be put on sale, it may be advantageous to fix the same by riveting instead of by sewing; an opening will then be provided in the center of the disks 1 and 4.

When the assembled button portions are subjected to a lateral pull, as happens when the parts of clothing a and F) which they connect together are stretched. there is some tendency to tilt in the direction shown in Fig. 3, but such tendency is checked by the resistance of the curved projections 5; the bead or bul e of the head 2 has a tendency to engage further underneath the projections located at the right side but it remains in contact with the other projections and the latter oiler a resistance quite sufficient to subdue the tilting strain set up by the pull, such strain being all the less as the direction of the pull indicated by arrow T passes nearer to the point of support 0 of the head on the right projection and as the diameter of such head is greater. There is thus obtained a perfectly safe fastening for clothing parts.

In the second embodiment, the star shape-d blank which serves for the manufacture of the female portion (Fig. 4) comprises four projections 5 having semi-circular ends and, at the lower parts of such projections there are small projections 8 in which are provided holes 7" which serve to sew the button portion to the garments. In the first stamping stage, the projections are made to stand vertically (Fig. 5) g in the second stage, the ends of such projections are curved or rolled inwardly (Fig. 6); in the third stage, the

said projections are so moved inwardly that the standing parts are inclined toward the center (Fig. 7) lastly in the fourth stage,-

outwardly; L116 holes '7 now lie at the bot tom of the spaces between the rolled projections and in a circle preferably somewhat larger than the inner circle of the orifice or opening of the button portion. The male button portion (Fig. 9) consists of a disk 1 the central part of which is so chased as to form a circular bulge or head 2 the side of which is bent in; the peripheral part is so stamped out as to form a ring 9 the section of which is semi-circular; in the intermediate portion comprised between the two previous parts are provided holes 3" which serve to sew the button portion to the garments. The number of the star projections may variable. The shape of the projections 5 just described enhances their. elasticity and also their resistance to the strain of the pull made transversely with respect to the axis of the button portion.

In the third embodiment shown in Figs. 10 to 12, the female portion consists of a disk 4: having at its 1 )eriphery projections 5 which are inwardly bent and curved in the manner described with reference to Figs. 4 to 7, the ends of such projections being in the shape of rollings 6" which form together a yielding ring the outer diameter of which is somewhat less than that of the disk 4"; such rollings are separated from one another by small spaces which allow of their contraction under the influence of a pressure from without and alsoullow the easy passage of the needle and thread through the holes 7" provided in the disk, on the latter being secured to the cloth by sewing. In the embodiment shown. the disk 4" is secured to the cloth. by means of a. riveted button The female portion 10, the cloth being clamped between the disk and the base of the button while the head of the latter is riveted to the disk. The male portion (Figs. 10 and 11) is made up of a disk 1 so stamped as to form a sort of collar 2* terminating in an annular ring 2, such collar and such ring being divided by slits which allow of their yielding sutiiciently. The outer diameter of such ring 2 is somewhat larger than the inner di ameter of the ring 6. Furthermore. the disk 1 is provided with a central opening serving to receive an eyelet 12 which secures the same to the cloth a. The periphery of the said disk is also so upset and turned down as to form a ring 13 designed to surround the ring 6" when the button portions are assembled together. The inner diameter of such ring 13 .is somewhatshorter than the outer diameter of the ring 6, so that it required a certain amount of axial pressure to engage the ring 6 between 1 3 and 2"; the annular space comprised between these two latter parts is of a depth just sul'iicient to receive the ring (3 completely.

It will be seen by Fig. 10 that the fixing together thus obtained runs no risk of being destroyed by any pull on the cloth (6, Z) in the direction of their planes, however hard such pull may be. Yet the strain in the direction of the axis of the button portions for opening and closing purposes is relatively slight by reason of the transversal yielding of the parts engaged with one another.

Claim:

In a pressure button a female member consisting of a disk having branches at its pcriphery, such branches being inwardly bent and curved so that their ends form rollings, such rollings forming together a divided ring and being staaarated from one another by small spaces, and the said disk having holes located in front of such spaces, substantially as described and shown.

In testimony. that I claim the foregoing as my invention I "have signed my name in presence of hvosubscribing Witnesses.
